The purpose of the present study lied in examining the incidence, treatment and failure causes of peri-implantitis by analyzing medical charts of those patients who underwent implant placement for the past 2 years. The subjects included those patients who underwent implant placement at the present hospital from January 2001 to December 2002. 3i implants were used for the analysis for the comparison of significance. A total of 301 patients were examined, among whom 102 were females and 199, males. Implants were placed in a total of 578 cases. The number of peri-implantitis was present in a total of 29 cases (21 males and 8 females), giving the incidence at 9.6%. The evidence of peri-implantitis was seen in 60 cases, which was in 10.4% of the patients. Among those cases with peri-implantitis, 28 cases (47%) underwent bone graft and 22 cases (43%) underwent maxillary sinus lift. Furthermore, 4 of these patients had systemic diseases such as diabetes or hypertension. Regular management is important for the preven ion of peri-implantitis. In other words, early prevention through regular follow-ups to check the status of surrounding soft tissue would be needed to maintain implants.

This study has been attempted using the Q methodology to clarify leader type of nurse managers that head nurses and general nurses recognize, and to clarify its relative relation. Sixty-three statements were extracted through interviews with general and professional people interested in the subject of nurse leaders to extract the Q population. Atotal of 314 Q population was formed added with 251 questions extracted from related documents. Final 32 Q samples were selected by reorganization of 314 Q population after reexamining statements through inquiry of 1 professor of the nurse department, 2 students in course of nurse science masters degree and 2 students in course of doctoral degree. The P sample selection standard of this study were 25 nurses and 30 head nurses. Examination subjects themselves filled out 32 statements classified in a measure of 9 points from agreeable items to disagreeable items, Principal component factors were analyzed using the QUANL pc program after grading the contents of the P sample. Nurses recognizing subjective structure for leader behaviors of nurse manager were analyzed to be 3 factors: vision presentation type, self-capability consideration type, relationship consideration type, and head nurses recognizing subjective structure were analyzed to be 2 types ; task pursuit leader type, and concord pursuit type. Nursing manager's leader behavior, expected by staff nurse are more complex and higher level which may combined with task pursuit leader type in concord pursuit leader of head nurse. Also according to Hersey and Blanchard theory(1977), the effectiveness of leadership becomes to be larger as the accordance rate between the behaviors of nurse leaders and followers reaction increase. Two suggestions have been made based on the conclusion. 1. Studies on creating strategies in relation to development, management, selection of nurse leaders should be made based on this study. 2. There is a need for relative study of production and degree of similarity of leadership types based on this study.

PURPOSE: This study was conducted to evaluate successful aging (SA) in elderly individuals and to determine the factors that influence SA. METHODS: The subjects included 207 elderly individuals from D city, Korea. The data were obtained between July 1 and August 30, 2008. The participants were assured of anonymity and confidentiality. For the evaluation, Kim & Shin's SA scale, Lawton's instrumental activities of daily living (IADL) scale, Jon's self-esteem scale, Kee's geriatric depression scale short form-Korean (GDSSF-K), and Hong's productive activities scale were used. The data were analyzed using descriptive statistics, the t-test, analysis of variance (ANOVA), and Pearson correlation coefficients; multiple regression analysis was performed using the SPSS/WIN 10.0 program. RESULTS: The maximum score for SA was 34, and the mean score was 22.62. It was found that SA was significantly correlated to IADL, self-esteem, depression, and productive activity. Depression was the most powerful predictor of SA and it accounted for 40.6% of the total variance in SA. Self-esteem, productive activity, living situation, economic status, and age together accounted for 62.1% of the total variation in SA. CONCLUSION: Depression, self-esteem, and productive activity were identified as variables that influence SA. On the basis of these results, we conclude that nurses should assist elderly individuals in order to facilitate SA. Moreover, individualized nursing management strategies must be developed in order to facilitate SA.

Laryngoscopy and intubation cause an adrenergic response manifested by tachycardia and hypertension. Various phamacological agents have been administered prior to induction in an attempt to attenuate the adrenergic response but they all have limitations. The objective of our study was to determine if esmolol would be equally effective when adrninistered in a bolus with and without fentanyl. A double-blind, randomized trial was conducted in sixty ASA physical status 1 patients undergoing elective surgery. All patients were premedicated with 0.2 mg/kg diazepam orally and glycopyrrolate 0.04 mg/kg intramuseularyly 1 hour beforehand. Induction of anesthesia was accomplished with 4 mg/kg thiopental intravenously foUowed immediately by 0.15-0.2 mg/kg vecuronium and study drug (placebo, esmolol 150 mg, esmolol 150 mg and fentanyl 100 mcg). Endotracheal intubation was performed at 2 minutes after study drug adrninistration. Anesthesia was maintained with 1 MAC (+/-10%) isoflurane in 60% nitrous oxide in oxygen at a 5 L/min flow for 6 minutes. Heart rate and blood pressure were measured every minute by an automatic recording device. After laryngoscopy and intubation, maximum increase in stolic blood pressure above awake levels was 33 mmHg (p<0.05) and 14 mmHg (p<0.05) in esmolol 150 mg, esmolol 150 mg with fentanyl 100 mcg respectively, whereas systolic blood pressure increased 62 mmHg after tracheal intubation in patients with placebo. In six patients with esmolol 150 mg, rate-pressure product reached a level considered potentially dangerous to patients with coronary artery disease. However, when used with fentanyl, esmolol provides effectvie protection against the adrenergic response and increase of the rate-pressure product to laryngoscopy and intubation.

PURPOSE: The effect of PTK inhibitors (herbimycin A and genistein) on the induction of radiation-induce d apoptosis in Ph-positive K562 leukemia cell line was investigated. MATERIALS AND METHODS: K562 cells in exponential growth phase were irradiated with a linear accelerator at room temperature. For 6 MV X-ray irradiation and drug treatment, cultures were initiated at 2x10' cells/mL. The cells were irradiated with 10 Gy. Stock solutions of herbimycin A and genistein were prepared in dimethyl sulphoxide (DMSO). After incubation at 37C for 0-48 h, the extent of apoptosis was determined using agarose gel electrophoresis and TUNEL assay. The progression of cells throughth the cel l cycle after irradiation and drug treatment was also determined with flow cytometry. Western blot analysis was used to monitor bcl-2, bcl-X and bax protein levels. RESULTS: Treatment with 10 Gy X-irradiation did not result in the induction of apoptosis. The HMA alone (500 nM) also failed to induce apoptosis. By contrast, incubation of K562 cells with HMA after irradiation resulted in a substantial induction of nuclear condensation and fragmentation by agarose gel electro-phoresis and TUNEL assay. Genistein failed to enhance the ability of X-irradiation to induce DN A fragmentation. Enhancement of apoptosis by H MA was not attributable to downregulation of the bcl-2 or bcl-X anti-apoptotic proteins. When the cells were irradiated and maintained with HMA, the percentage cf cells in G2/M phase decreased to 30-40% at 48 h. On the other hand, cells exposed to 10 Gy X-irradiation alone or maintained with genistein did not show marked cell cycle redistribution. CONCLUSION: We have shown that nanomolar concentrations of the PTK inhibitor HMA synergize with X-irradiation in inducing the apoptosis in Ph (+) K562 leukemia cell line. While, genistein, a PTK inhibitor which is not selective for p2 10""'' failed to enhance the radiation induced apoptosis in K562 cells. It is unlikely that the ability of HMA to enhance apoptosis in K562 cells is attributable to bcl-2 family. It is plausible that the relationship between cell cycle delays and cell death is essential for drug development based on molecular targeting designed to modify radiation-induced apoptosis.

PURPOSE: To assess the efficacy and safety of selective laser trabeculoplasty (SLT) as initial and adjunctive treatment for ocular hypertension and open angle glaucoma. METHODS: Twenty-four eyes with ocular hypertension and 63 eyes with open angle glaucoma were treated with a frequency-doubled, Q-switched Nd:YAG laser. Intraocular pressure (IOP) was measured prelaser treatment, one week, one, two, three, six, 12, 18, and 24 months after treatment. RESULTS: The average pre-laser IOP of 87 eyes was 21.6 mmHg. The mean IOP percent reductions at 1 week, one, two, three, six, 12, 18, and 24 months were 15.3%, 20.0%, 21.3%, 19.6%, 23.4%, 23.4%, 20.5%, and 20.9%, respectively. The IOP percent reductions in the initial treatment group at one, 12, and 24 months were 21.1%, 24.8%, and 22.8% respectively. The IOP percent reductions in the adjunctive treatment group at 1, 12, and 24 months were 19.6%, 22.9%, and 20.2% respectively. There were no differences in IOP percent reduction between the initial treatment group and the adjunctive treatment group. CONCLUSIONS: Selective laser trabeculoplasty has shown reasonable efficacy in lowering IOP over two-year follow-up period as initial and adjunctive treatment for ocular hypertension and open angle glaucoma.

The incidence and etiology of parasite-associated gastroenteritis during 2004-2006 in Gyeonggi-do (province), South Korea was determined by means of antigen detection ELISA on 6,071 stool specimens collected from 6 general hospitals. At least 1 parasitic agent was detected in 3.4% (208/6,071) of the stool samples. Among these, Giardia lamblia was the most numerous (152 cases; 2.5%), followed by Entamoeba histolytica (25 cases; 0.4%), Cryptosporidium parvum (23 cases; 0.4%), and mixed infections (8 cases; 0.1%). Patients aged 1-5 years had the largest proportion (69.2%; 144/208) of parasite-positive stool specimens. Parasite-mediated gastroenteritis was most common from June to September. The detection rate gradually increased from 2004 to 2006. This study shows that parasite-mediated gastroenteritis may be significant among children in Korea and that parasite infection surveillance should be constantly performed.
